[0028] Reference Figures 1 to 3 , a vehicle door hinge structure, comprising:

[0029] A mounting base 10, which can be mounted on a vehicle body, is provided with first, second and third rotating bases 11, 12, 13;

[0030] The first rotating part 20 has one end rotatably connected to the first rotating seat 11 to form a first rotating axis 61 for adjusting the height of the door;

[0031] The second rotating part 30 has one end rotatably connected to the second rotating seat 12 to form a second rotating axis 62 for adjusting the door opening;

[0032] The third rotating part 40 has one end rotatably connected to the third rotating seat 13 to form a third rotating axis 63 for adjusting the height of the door;

[0033] The swing seat 50 can be connected to the vehicle door, and has a first rotating end 51 rotatably connected to the other end of the first rotating part 20, a second rotating end 52 rotatably connected to the other end of the second rotating part 30, and a third rotating end 53 rotatably connected to the other end of the third rotating part 40, so as to form a fourth, fifth and sixth rotating axes 64, 65, 66 respectively. The first, second, third, fourth, fifth and sixth rotating axes 61, 62, 63, 64, 65, 66 intersect at one point.

[0034] In the present invention, the first driving device 81 is rotationally connected to the end of the first swing arm 71 facing away from the second swing arm 72 through the first ball-and-socket structure, and the second driving device 82 is rotationally connected to the end of the second swing arm 72 facing away from the first swing arm 71 through the second ball-and-socket structure. When the door is opened, the first driving device 81 drives the end of the first swing arm 71 facing away from the second swing arm 72 to move downward, and the second driving device 82 drives the end of the second swing arm 72 facing away from the first swing arm 71 to move upward. The various components move in coordination around the first, second, third, fourth, fifth and sixth rotation axes 61, 62, 63, 64, 65 and 66, thereby realizing the upward and downward movement of the door. Open outward; specifically, the first rotating part 20 can adjust the height of the door opening, the second rotating part 30 can adjust the degree of the door opening, and the third rotating part 40 can adjust the height of the door opening, so that the third rotating part 40 can exert better pulling force and supporting force on the second swing arm 72 when the door is opened upward and outward, especially under high temperature (60°C), gas springs and other components will have insufficient supporting force for the door due to thermal attenuation, and the third rotating part 40 and the fifth rotating axis 65 and the sixth rotating axis 66 can make the door open more smoothly, bringing a better user experience.

[0035] The intersection points of the first, second, third, fourth, fifth and sixth rotation axes 61 , 62 , 63 , 64 , 65 , 66 are located on the first rotation part 20 .

[0036] The swing seat 50 includes a first swing arm 71 and a second swing arm 72 connected to the first swing arm 71 . The first and second rotating ends 51 , 52 are arranged on the first swing arm 71 , the third rotating end 53 is arranged on the second swing arm 72 , and the vehicle door is connected to the second swing arm 72 .

[0037] A vehicle door hinge structure also includes a first driving device 81 having one end rotationally connected to the vehicle body and the other end rotationally connected to the first swing arm 71 .

[0038] The first driving device 81 is an electric support rod.

[0039] A vehicle door hinge structure also includes a second driving device 82 rotatably connected to the vehicle body at one end and rotatably connected to the second swing arm 72 at the other end.

[0040] The second drive device 82 is configured as a gas spring.

[0041] The second swing arm 72 is connected to the first swing arm 71 through a plurality of connection points 90; the second swing arm 72 extends along the height of the vehicle door, and the number of connection points 90 is set to at least two and arranged along the length direction of the second swing arm 72; by setting a plurality of connection points 90 between the first swing arm 71 and the second swing arm 72, when the first drive device 81 drives the first swing arm 71 to move, the force applied to the first swing arm 71 can be more evenly transmitted to the second swing arm 72, thereby better opening the vehicle door; through the cooperation of the first drive device 81 and the second drive device 82, the vehicle door can be hovered at any position, bringing a better user experience.

[0042] A vehicle comprises the door hinge structure.

[0043] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
